Shamrock Holmes may not have a progressive jackpot like other games, but seeing as you can win 28,000x your stake on a single spin, that’s a top prize worth keeping your eye out for! You can trigger this huge amount by racking up unlimited multipliers during the bonus round, giving your payouts a mega boost.


Shamrock Holmes Megaways features up to 117,649 ways to win with 7 reels. You’ll notice reels 2, 3, 4, and 5 extend slightly above the rest, making way for an extra set of symbols. Your objective is to spin the reels and land winning combinations of matching symbols. Unlike slots with paylines, matching symbols only need to be adjacent to each other, starting from left to right to trigger a payout.

The rolling reels feature activates after a winning spin in both the base game and the bonus round. Winning symbols disappear from the reels, and new ones drop down from above. You can trigger consecutive rolling reels if you keep winning. The rolling reels feature stops automatically after a no-win spin.

  • Coin sizes / how the betting system works: The minimum bet size available is $0.20 per spin, while the maximum bet is $20.
  • Symbols: All of the symbols are Celtic-themed and can appear as regular 1x1 symbols or stacked 1x3.
    • Standard: Shamrock is the highest paying regular symbol. Landing 6 at the same time pays 50x. The Pot of Gold is worth up to 5x, the Clover is worth up to 2.50x, and the flower is worth up to 2x. The low-value symbols are royal cards A-9 and worth up to 1.5x.
    • Wild: The wild symbol can substitute for all regular symbols to help create winning combinations but only appears as a 1x1 symbol in the extra reel at the top of the grid.
    • Scatter: When 4 scatter symbols appear simultaneously, you’ll trigger the free spins feature with 10 free spins. Every additional scatter symbols adds an extra 2 spins. You start the round with a 2x win multiplier, which increases with each rolling reel and there’s no limit to how high it can go. Landing 3 scatters during the feature gives you 3 extra free spins, while 4 scatters gives you another 4 free spins.
